Assign properties to the material

class Material(name, description='', materialIdentifier='')

基类：MaterialBase

A Material object is the object used to specify a material. The Material object stores the various settings that determine how a material behaves. A material is created by combining one or more individual material options and sub options. A particular material option is associated with the Material object through a member. For example: the acousticMedium member may contain an AcousticMedium object. The alternative of having a MaterialOption abstract base class and a container of MaterialOptions was rejected because it would make it more difficult to enforce the fact that one Material object cannot contain two AcousticMedium objects, for example.
